IMPROVEMENT IN UHURNS.

TO'ALL WHOM IT MAY CONCERN: v

Be it known that I, WILLIAM'T. BEST, of Scranton, inthe countyof Luzerne, and in the State of Pennsylvania, have invented certain new and useful Improvements in Ohurns and do hereby declare that the following is a full, clear, and exact description thereofireference being had to the accompanying drawings, and to the letters of reference marked thereon.

-In the annexed drawings, making part of this specification, A represents a churn-body, which may bemade of wood or metal, and in any of the well-known and usual ways. Over the mouth of this churn-body, and extending down into it, is a supplementary box, B, which I intend for the purpose of breaking the cream before it enters the churn proper. The box B is provided with an inclined or converging bottom, a a. Secured in this bottom a is a cylinder, 0, abont one-half of said cylinderrunning above and the other half below its point of contact with the bottom. This cylinder stands in a vertical position, and has its lower half and bottom perforated with many holes, or madeof gauze wire. The upper end of the cylinder is open, and its sides above the bottom a are slotted to allow the'cream to pass into it. -An annular slotted band is passed around the cylinder, over that portion of it which is slott'ed, and this band is adjustable,'acting as a gate to open or close the slots to regulate the amount of cream which passes in. I V r V E represents a dasher-stafi', which-is provided upon its lower end with a'series of breaker's'or wings, vh F. This staif has one bearing in the bottom of the cylinder and one in the'box-cover'I Upon the upper end of this stafl' is secured a'bevel-wheel, G, which ,g'ears into a bevel-wheel, H, on a shaft, I. The shaft I lies in a horizontal position, and has its bearings in a-suitable frame erected-upon the churn-cover K, and is provided either with a crank-shaft'or a pulley wheel, by me'ans of which it is revolved. The cover K is provided with a funnel, P, and a covered opening at J; The cream :isjpoured in through the funnel, and its operation maybeobscrved through the opening at J. The form of the breakers F is curved as represented in fig. 3.

Inchurning cream or milk with this churn, there are two operations. The first isbreaking the cream with the device just described. The stafi', with its breakers, being set in motion by means of the gea1'-wheels, the cream is poured into tliebOX B through th ejfunnel P, and, falling upon the bottom, a, is admitted in such quan titics to the cylinder, by the gate surrounding said cylinder, as is desirable. The breakers F F revolving rapidly, out and break the cream, and rupture many of its globules,'and foree it through the perforations in the lower part ofthe cylinder; thence it fallsto the bottom of the churn proper. I

As soon as the cream has all been run through-the breaking-cylinder, the supplementary box B is removed, and a frame, N, is placed inthe churn; This frameconsists of two skeleton-heads connected by suitable perforated standards. The lower'head is provided with a rim, e, around it, a nd also with a number of'holes. It i has a square hole in. its bottom, which fits over a square plug or projection which is secured in the bottom of the.churn, and is thus prevented from revolving orbeing displaced.

L represents the churn-staff, which is provided with dashers of any desirable construction, M M represent ing said dashers. A cross-piece, o, crosses the upper head of frameN, and has a'.hole in it,.thro ugh which stafi' L passes. The cover K answers both as a cover for the box 13, and also-for the churn. The staff L runs up through cover K, and is provided upon its upper end with the bevel-wheel G. This bevel-wheel is made adjnst= able and so that it can be secured to the stafi's by means of athumb screw. The staii' L is revolved by the wheels G and H in a manner similar to that already described for staff E.

When the cream has been churned by the dashers M, and the butter has been well broken and is ready to be removed, I remove thecover K and lift out the stafi' M. I then lift the frame N, and, as its lower head forms a perforated pan or cup, the butter remains in it and is drawn from thechurn, while the buttermilk runs through the perforations and returns to the churn. This mode of removing the butter is very simple, easy, and effective.

Of course, during the operation of churning, can make observations through the opening at J, and can supply hot or cold water through the funnel P, as the nature of the case may require.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The supplementary box B, having a converging bottom, and being provided with the slotted and perforated cylinder 0, and used-with the stafi E and its breakers, as and for the purpose set forth.

7 2. The frame N, constructed substantially as described, and provided with a rim around its lower end for collecting the butter, said frame being used in the churn A'and with the stafliL and its dasher's ss and for the purpose specified.

3. The gate d, surrounding the slotted portion of I cylinder 0, for regulating the new of cream to said cylinder, substantially as herein specified.

Intestimony that I'claim the foregoing, I have hereunto set my hand, this 2d day of April, 1868.
